Which function measures a numeric value's distance from 0?

ACONCAT

BLOWER

CFROM

DABS

Show Suggested Answer

Suggested Answer: D

The ABS() function in SQL returns the absolute value of a given number, effectively measuring its distance from zero.

Example Usage:

sql

SELECT ABS(-50), ABS(50);

Result:

50 | 50

This function ensures that numbers are always positive, regardless of their original sign.

Why Other Options Are Incorrect:

Option A (CONCAT) (Incorrect): Used to combine strings (not numbers).

Option B (LOWER) (Incorrect): Converts text to lowercase, not numerical operations.

Option C (FROM) (Incorrect): Part of SELECT FROM queries, not a function.

Thus, the correct choice is ABS(), which computes the absolute value of a number.

The ABS function is like a bouncer at a club - it doesn't care if you're positive or negative, it just kicks you out and gives you the distance from 0.

I feel like LOWER has to do with text, so it can't be the right choice. ABS seems most likely.

The ABS function, that's the one! It returns the absolute value, which is the distance from 0. I remember learning this in class.

I'm not sure about this. Is it the FROM function that measures distance from 0? I'll have to review this concept again before answering.
